The purpose of this standard is to establish minimum requirements for control of infectious aerosols to reduce risk of disease transmission in the occupiable space in new buildings, existing buildings, and major renovations to existing buildings, including requirements for both outdoor air system and air cleaning system design, installation, commissioning, operation, and maintenance.
This standard defines the amount of equivalent clean airflow necessary to substantially reduce the risk of disease transmission during infection risk management mode.
This standard addresses only indoor long-range transmission resulting from inhalation of infectious aerosol emitted by an infector who is not in close proximity to a susceptible occupant.
Testing Requirements. The effectiveness and safety of cleaning systems shall be determined by testing an air cleaning system or equivalent system in accordance with Section 7 and Appendix A.
